    I have just finished editing my captured DV files and the resulting movie
    length is about 1 hour long. I believe that you can fit more than an hour
    onto a DVD-R disk therefore I would be grateful if somebody could advise me
    what woud be the maximum attributes I can assign to the movie editor in
    order to produce the best quality DVD mpeg file to maximise the use of the
    disk. Thank you

    First of all, you have to use the best mpeg2 encoders on the market,
    that is TMPGEnc or CCE. I suggest TMPGEnc because it has a wizard, a
    very good Constant Quality method and you can adjust the quality/size to
    fit before the start of encoding, and it is more or less very intuitive.
    That means that you first have to export your edited movie in DV format
    back to the HDD (from Premiere, Studio, ...) in order to impoer that DV
    avi file to the TMPGenc encoder. Then, there are few other settings to
    maximise the quality, i.e.:
    * DC precision = 10 bits
    * Motion estimation = High (not highest, very slow)
    * Compression method (Constant Quality = 85)
    * Disable all filters

    This should give you very good results, and a file size near 4Gb which,
    after you import that mpeg2 file into a DVD authoring program, including
    menus should be near DVD capacity (4.38Gb).

    Thanks for your help, I was hoping to use the video editor that came bundled
    with my capture card (MGI Videowave). Just checked out the TMPGenc site -
    looks good, will start saving...In the meantime is there any general
    settings to look out for as I'm fairly new to all this.

    Does the full version of Vegas Video export to Mpeg2, or is it an

    I don't know about this Videowave, but the most know video editors are
    Pinnacle Studio 9, Ulead Video Studio, Adobe Premiere and a few more.
    Studio is IMHO preferred choice for the beginners, for it offers
    complete job from DV capture to DVD burning, and a decent quality too.
    I'm still working with it and I am pretty satisfied. You should
    definitely give it a shot.

    As for general settings, more bitrate, more quality. In general, above
    8000 kbps (kilobits of video per second) should be fine, and with this
    bitrate you'll fill up one DVD with one hour of video. If there is any
    compression method, allways select 2pass(es). More passes, more quality
    (in most scenarios).

    I "think" you have to have DVD Architect to be able to do this. I have both
    so I'm not sure.
    Check the Sony site for verification.
    By getting it, you also have AC3 support which allows you to increase your
    overall bit rate as your audio files are much smaller.

    Hi Mitch,

    It's included with version 5. For previous versions it was an add-on.

    Here's a comparison chart. The MPEG stuff is located near the bottom.

    It's not clear what "the movie editor" is. But, you want this to be
    DVD-Video compliant, correct?

    If so, then you need to remember a couple things:

    1. The maximum video bitrate is 9.8Mb/s, while the total bitrate is
    10.08Mb/s (I'm talking MPEG-2 here).
    2. DUPLICATED or BURNT discs **tend** to not work universally well in
    standalone players when the total bitrate is >7-8Mb/s, so to keep it as
    safe as you can, don't go higher than that. NOTE: Some players have no
    problem with the full DVD-Video bitrate listed above, while others will
    barf. This does NOT apply to REPLICATED discs.

    With that in mind, grab a bitrate calculator such as Bearson's BitRate
    Calculator. Plug in the length (time) of the footage, use 4425MB* for the
    size of a 4.3GB DVD-R, and then plug-in the audio bitrate. What is left
    over is what you have left for the video. Encode at multi-pass VBR using
    that bitrate as an average (low=192Kb/s, high=9800Kb/s**) for best
    quality. I do this all the time to determine the bitrates I will use.

    * This number works well for me while leaving just a little slack. A lot
    of it depends on how accurately your MPEG encoder strictly respects the
    target bitrate. Feel free to experiment and nudge it up a bit higher to
    more fully maximize the disc space. If you try to go much higher than
    that, you may end up with assets that are just larger than a full DVD-R
    and that sucks.

    ** Keeping in mind (2) above, you may need to drop that to 7000-8000Kb/s.

    After getting the above numbers, I have a few guidelines (not hard, fast,
    unbreakable rules) I decide on how to encode if I want something to fit on
    one 4.3GB DVD-R (i.e., not willing to split to multiple discs and I don't
    have a DVD+R DL burner):

    If the average video bitrate is >4Mb/s, I typically encode full D1 to VBR
    MPEG-2. If the average video bitrate ends up being 2.5Mb/s - 4Mb/s, I
    tend to encode to half D1 VBR MPEG-2. If the average video bitrate ends
    up being less than 2Mb/s, I encode to Quarter SIF CBR MPEG-1 at a high of
    a bitrate as possible, but no higher than 1.856Mb/s.

    Any other questions?
